Before you read on — a word about potassium and prescriptions

Cream of tartar is a concentrated source of potassium. That is the point of it, and for most people it is unremarkable. But potassium is one of the few minerals where more is not automatically better, and a handful of common prescriptions change how your body holds on to it.

Talk to your doctor or pharmacist before adding Tarsul if you take a potassium-sparing diuretic (spironolactone, triamterene, amiloride), an ACE inhibitor (lisinopril, enalapril, ramipril), an ARB (losartan, valsartan, irbesartan), a potassium supplement or salt substitute, or regular NSAIDs — and if you have reduced kidney function or have been told to watch your potassium, ask first. It is a five-minute conversation and worth having.

And please do not stop, reduce, or replace a prescribed medication on your own. Nothing on this page is a reason to change what your doctor put you on. If you want to discuss it, discuss it with them. Fuller detail on serving sizes and precautions is on our dosage and precautions page.

Natural Supplement for Hypertension: Addressing the Root Cause of High Blood Pressure

Discover why simply forcing your blood vessels open is not enough, and how restoring foundational mineral balance supports long-term cardiovascular health.

The Hidden Reality of High Blood Pressure

If you have been diagnosed with hypertension, you likely know the standard protocol: reduce sodium, manage stress, and prepare for a lifetime of medication. But this approach often misses the fundamental question: why is your body increasing the pressure in the first place?

High blood pressure is rarely a random malfunction. It is a biological adaptation. When your cells are starved of oxygen or essential nutrients, your heart pumps harder and your vessels constrict to force that vital supply where it needs to go. Simply taking a pill to artificially relax those vessels or slow your heart rate treats the symptom, but it ignores the underlying cellular distress.

What if your high blood pressure is actually a warning sign of a severe mineral deficiency?

The Role of the Sodium-Potassium Pump

At the cellular level, your blood pressure is heavily regulated by a mechanism called the sodium-potassium pump. This microscopic engine exists in every cell of your body, including the smooth muscle cells that line your blood vessels. Its job is to pump sodium out of the cell and pull potassium in.

Cream of tartar and MSM sulfur powder, the two ingredients in Tarsul, in the context of blood pressure and circulation — Tarsul is a fine white powder — potassium bitartrate (cream of tartar) combined with MSM sulfur — stirred into water rather than swallowed as a tablet.

When this pump functions correctly, your blood vessels remain relaxed and flexible. But here is the problem: the modern diet is overwhelmingly high in sodium and critically deficient in potassium. When you do not have enough potassium, sodium builds up inside the cells of your blood vessel walls. This causes them to absorb water, swell, and constrict—driving your blood pressure up.

Why Tarsul is Different

Tarsul was formulated to address this specific, widespread deficiency. By combining Organic MSM Sulfur with Cream of Tartar (a highly bioavailable source of Potassium Bitartrate), Tarsul provides the foundational elements your cardiovascular system needs to regulate itself naturally.

Potassium for Cellular Balance: The potassium in Tarsul helps reactivate the sodium-potassium pump, allowing your blood vessels to release excess sodium and naturally relax.
Sulfur for Vascular Integrity: MSM Sulfur is essential for the production of collagen and elastin—the proteins that keep your blood vessels flexible and resilient. Stiff, rigid arteries cannot expand to accommodate blood flow, which forces pressure up. Sulfur helps restore that vital elasticity.
Inflammation Reduction: Chronic inflammation damages the delicate lining of your blood vessels (the endothelium), impairing their ability to produce nitric oxide, a natural vasodilator. MSM Sulfur is a powerful anti-inflammatory that helps protect this critical lining.

Breaking the Cycle

Many people find themselves on a frustrating merry-go-round of adjusting dosages and adding new prescriptions as their body builds a tolerance to blood pressure medications. This happens because the root cause—mineral deficiency and vascular stiffness—was never resolved.

Tarsul 60-capsule, 600 gram and 150 gram bottles, the sizes referred to in this natural supplement for hypertension guide — Tarsul is sold in a 150 gram bottle, a 600 gram bottle and a 60-capsule bottle. Dosing guidance is on the ingredients page.

By providing your body with the potassium it needs to balance sodium, and the sulfur it needs to maintain flexible, healthy blood vessels, you are supporting your cardiovascular system at a foundational level. You are giving your body the tools it needs to regulate pressure naturally, rather than forcing it into submission chemically.
